Description

Technical Field

[0001] This application relates to the technical field of extrusion machine shaft speed measurement. Specifically, it relates to a device and adjustment method for facilitating the gap adjustment of speed sensors and rapid re-inspection. Background Art

[0002] In the field of extrusion machine speed detection, the gap accuracy between the speed sensor and the speed measurement block is crucial for the measurement result. The traditional installation method has many drawbacks: usually, manual adjustment of the position of the speed sensor is relied on. After the set gap (requirement: 3 mm) is reached with the speed measurement block, two locking screws are used for fixation. During this process, the operator needs to hold the sensor with one hand and tighten the nut with the other hand, which is very likely to cause the sensor to be skewed or displaced, affecting the speed measurement accuracy. Moreover, this operation has high requirements for personnel skills, poor assembly processability and reliability, and is even more difficult to implement when the assembly space is cramped.

[0003] Due to the limited rotation of the motor and gearbox, it is difficult to ensure that the detection block is directly above the sensor to achieve precise gap setting, resulting in time-consuming and laborious installation, and unable to ensure that multiple (such as 3) detection blocks can meet the set gap requirements. Once the gap is not properly controlled, being too large or too small will cause the speed signal to be distorted. In severe cases, the extrusion machine will lose the speed signal, triggering an abnormal interlock shutdown and causing production accidents. If the gap is too small, it may also cause the speed measurement block to collide with the sensor, damaging the sensor, further exacerbating the risk of production interruption, increasing the maintenance cost and time loss. Therefore, there are deficiencies. Summary of the Invention

[0004] To make up for the above deficiencies, the present invention provides a device and adjustment method for facilitating the gap adjustment of speed sensors and rapid re-inspection, aiming to improve the situation that due to the limited rotation of the motor and gearbox, it is difficult to ensure that the detection block is directly above the sensor to achieve precise gap setting, resulting in time-consuming and laborious installation, and unable to ensure that multiple (such as 3) detection blocks can meet the set gap requirements.

Specific embodiments

[0035] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0036] As Figures 1 - 7 shown, the device and adjustment method for facilitating the gap adjustment and rapid re-inspection of the speed sensor according to the embodiment of the present application include:

[0037] Rotational speed sensors 1, there are three rotational speed sensors 1, and the three rotational speed sensors 1 are jointly arranged in a clamping assembly 8;

[0038] Support assembly 2, the support assembly 2 is fixedly installed on the upper part of the fixed base plate 7, and the top of the support assembly 2 is fixedly connected to the bottom of the clamping assembly 8;

[0039] Motor drive shaft 3, two relatively arranged speed measurement blocks 4 are fixedly connected to the side wall of the motor drive shaft 3, and the speed measurement blocks 4 are arranged in cooperation with the rotational speed sensors 1;

[0040] Gap adjustment assembly 5, the gap adjustment assembly 5 is arranged between the motor drive shaft 3 and the rotational speed sensor 1, the gap adjustment assembly 5 is detachable and separately arranged, and the gap precision adjustment is carried out through the innovatively designed movable gap adjustment assembly 5. Combining with the rotation detection mechanism of the motor drive shaft 3, it effectively solves the problems existing in the traditional installation method, such as difficult gap adjustment, low precision, easy damage to the sensor and causing production accidents, etc. It can significantly reduce the assembly complexity, accurately control the installation gap, greatly improve the work efficiency, and provide a reliable guarantee for the stable operation of the rotational speed detection system of the extruder, and has important application value and promotion prospects in industrial production.

[0041] As Figures 4 - 6 shown, data cables 19 are connected to the side walls of the three rotational speed sensors 1 through data splitters 20, and the data cables 19 are inserted downward into the support assembly 2 and extend outward.

[0042] As Figure 4 and Figure 6As shown, the clamping assembly 8 includes a fixed base 14 and a clamping plate 15. Three spaced clamping grooves are provided on the fixed base 14. The clamping grooves are arranged in one-to-one correspondence with the rotational speed sensors 1. The inner wall of the clamping groove abuts against the side wall of the rotational speed sensor 1. There are three clamping plates 15. The three clamping plates 15 are respectively fixedly connected to the side wall of the fixed base 14 through fastening bolts. The inner wall of the clamping plate 15 abuts against the side wall of the rotational speed sensor 1. The rotational speed sensor 1 is fixed between the fixed base 14 and the clamping plate 15. The depth of the clamping groove provided on the fixed base 14 is greater than the length of the rotational speed sensor 1. In this way, the rotational speed sensor 1 can adjust its position between the fixed base 14 and the clamping plate 15, avoiding the situation that the three rotational speed sensors 1 cannot cooperate with the movable gap adjustment block 6 to measure the distance during the initial installation, and the fixed position of the rotational speed sensor 1 can be flexibly changed.

[0043] Furthermore, a limiting block 16 is fixedly connected to the side wall of the fixed base 14. The limiting block 16 is arranged in cooperation with the clamping plate 15, avoiding the misalignment of the position of the clamping plate 15, which may cause the inaccurate installation of the clamping plate 15.

[0044] As Figures 4 - 6 shown, the support assembly 2 includes a support frame 9 and a movable frame 11, which can provide reliable support for the rotational speed sensor 1, greatly facilitating the operator to fix the rotational speed sensor 1 by tightening the bolts. It has low manufacturing cost and excellent installation processability, can significantly improve the installation efficiency and quality, reduce manual operation errors, and enhance the stability and durability of the installation of the rotational speed sensor 1. The bottom of the support frame 9 is fixedly connected with a connection base 13. The connection base 13 is fixed to the upper part of the fixed base plate 7 through a fixed bolt, clarifying the fixed position of the connection base 13. A borrowing slot is provided at the front of the support frame 9. Two fixing plates 10 are fixedly connected to the front of the support frame 9. The movable frame 11 is arranged in the borrowing slot. The top of the movable frame 11 is fixedly connected to the bottom of the clamping assembly 8. A fixing hole 12 is provided on the movable frame 11. The fixing hole 12 is fixedly connected to the fixing plate 10 through a reinforcing bolt.

[0045] Furthermore, a partition plate 23 is fixedly connected inside the support frame 9. The partition plate 23 can hide and divide the data cable 19, avoiding the damage of the data cable 19 by the movable frame 11 and playing a role in protecting the data cable 19.

[0046] Furthermore, a sliding groove 17 is provided at the bottom of the connection base 13. A pressing sleeve block 18 is slidably installed in the sliding groove 17, which can press the bottom end of the data cable 19, avoiding the random movement of the data cable 19, effectively limiting the position of the data cable 19, and facilitating the subsequent accurate connection.

[0047] As Figure 2 andFigure 7 As shown, the gap adjustment assembly 5 includes a movable gap adjustment block 6 and a magnetic gap adjustment block spacing standard block 24. The movable gap adjustment block 6 is arranged in cooperation with a plurality of rotational speed sensors 1. A clamping groove 21 is formed in the upper part of the movable gap adjustment block 6. The magnetic gap adjustment block spacing standard block 24 is arranged in cooperation with the movable gap adjustment block 6. The upper side wall of the magnetic gap adjustment block spacing standard block 24 is magnetically attracted to the side wall of the motor transmission shaft 3. The gap adjustment assembly 5 can replace the standard spacing block according to actual needs, and the movable gap adjustment block 6 and the magnetic gap adjustment block spacing standard block 24 which are designed to be disassembled are provided. The movable gap adjustment block 6 and the magnetic gap adjustment block spacing standard block 24 are basically the same in shape as the speed measurement block 4. The magnetic gap adjustment block spacing standard block 24 can be quickly and stably magnetically attracted to the side wall of the motor transmission shaft 3. At the same time, the movable gap adjustment block 6 can slide radially along the movement direction of the speed measurement block. Through the rotation of the motor transmission shaft 3, it is accurately ensured that the gap adjustment of the three rotational speed sensors 1 meets the requirements, effectively avoiding signal problems and equipment damage risks caused by uneven or inaccurate gaps.

[0048] Furthermore, two magnetic gap adjustment block spacing standard blocks 24 are symmetrically arranged above the movable gap adjustment block 6. A clamping block 22 is fixedly connected to the lower side wall of the magnetic gap adjustment block spacing standard block 24. The clamping block 22 is arranged in cooperation with the clamping groove 21, which is convenient for the clamping connection of the movable gap adjustment block 6 and the magnetic gap adjustment block spacing standard block 24, avoiding the separation of the movable gap adjustment block 6 and the magnetic gap adjustment block spacing standard block 24 during rotation, which affects the accuracy of spacing measurement. Magnetically attract the required magnetic gap adjustment block spacing standard block 24 to the side wall of the motor transmission shaft 3, and then assemble the other end with the movable gap adjustment block 6, so that the rotational speed sensor 1 contacts the lower end surface of the movable gap adjustment block 6. After pushing and adjusting to be determined, tighten the clamping assembly 8 to fix the rotational speed sensor 1. The other two rotational speed sensors 1 are carried out analogously. Finally, simulate the rotation of the shaft, slide the movable gap adjustment block 6, and comprehensively check again whether there are unreasonable installation gaps caused by the mutual influence of components during the installation process, and make fine adjustments and optimizations in a timely manner.

[0051] S2. Prepare the movable clearance adjustment block 6, the clearance adjustment block magnetic attraction spacing standard block 24, and three rotational speed sensors 1, and fix the rotational speed sensors 1 in the fixed base 14 and the clamping plate 15.

[0052] S3. Magnetically attract the clearance adjustment block magnetic attraction spacing standard block 24 to the side wall of the motor transmission shaft 3, engage the movable clearance adjustment block 6 with the clearance adjustment block magnetic attraction spacing standard block 24, and make the side wall of the movable clearance adjustment block 6 contact the top end of the rotational speed sensor 1.

[0053] S4. Push the motor transmission shaft 3 to rotate so that the top end of the movable clearance adjustment block 6 and the rotational speed sensor 1 are in a suitable position.

[0054] S5. Tighten the fixed base 14 and the clamping plate 15 to fix the position of the rotational speed sensor 1, and then rotate the motor transmission shaft 3 for a quick simulation re-inspection. After completing the inspection and optimization work, stop the rotation of the motor transmission shaft 3, and remove the movable clearance adjustment block 6 and the clearance adjustment block magnetic attraction spacing standard block 24 from the side wall of the motor transmission shaft 3. The time required to adjust the clearance between the rotational speed sensor 1 and the speed measurement block 4 is significantly shortened from the original 1 hour to 15 minutes.

[0055] Specifically, the working principle of the device and adjustment method for facilitating the clearance adjustment of the speed sensor and quick re-inspection: Assemble the required clearance adjustment block magnetic attraction spacing standard block 24 to the movable clearance adjustment block 6 so that the rotational speed sensor 1 contacts the lower end face of the movable clearance adjustment block 6. After pushing and adjusting to determine, tighten the fixed base 14 and the clamping plate 15 to fix the three rotational speed sensors 1, and then simulate the rotation of the shaft. Slide the motor transmission shaft 3 to drive the movable clearance adjustment block 6, and comprehensively check again whether there are unreasonable installation clearances caused by the mutual influence of components during the installation process, and make fine adjustments and optimizations in a timely manner. After the inspection is completed, install the speed measurement block 4 on the side wall of the motor transmission shaft 3. Therefore, this spacing adjustment device has significant advantages in actual operation, is easy to operate, occupies a small space, has relatively low technical requirements for operators, and is convenient for popularization and application in various production environments. Through ingenious design, it not only effectively reduces the difficulty of clearance adjustment but also greatly improves the control accuracy, bringing great convenience to the installation of the rotational speed sensor 1. At the same time, the rotation function of the motor transmission shaft 3 can comprehensively check the installation effect, ensure the long-term stable operation of the rotational speed sensor 1, and the movable clearance adjustment block 6 and the clearance adjustment block magnetic attraction spacing standard block 24 for installing the clearance adjustment have low manufacturing costs, good installation processability, high cost performance and practical value, and can effectively improve the production efficiency and equipment management level of enterprises.
